Description
  • Neni znama. (cs)
  • We present a novel framework for efficiently computing the indirect illumination in diffuse and moderately glossy scenes using density estimation techniques. Many existing global illumination approaches either quickly compute an overly approximate solution or orders of magnitude more slowly compute high-quality results for the indirect illumination. The proposed method improves photon density estimation and leads to significantly better visual quality in particular for complex geometry, while only s lightly increasing the computation time. We perform direct splatting of photon rays, which allows us to use simpler search data structures. Our novel li ghting computation combines photon splatting and density estimation. Since the density estimation is carried out in ray space rather than on surfaces, as in the commonly used photon mapping algorithm, the results are more robust against geometrically incurred sources of bias.
